I got a bunch of responses back on the sunlight reflection options message I sent. And I wanted to share about what I heard back from other people in this community:

• One person wrote that sunlight reflection methodologies should stay as the last possible resort and they felt sad to hear me talking about them

• Another sent this NASA study about a giant dust cloud in space to reflect sunlight

• Another liked the idea of a planetary sunshade with solar panels on it to put the sun's energy to use

• Another said that they liked marine cloud brightening because it had a short term effect in a few days so it could be easier to evaluate

When I started working on carbon dioxide removal, I had this feeling that things were about to move quickly and that there was something I could add. I'm getting the same feeling about sunlight reflection now, alongside my work in carbon dioxide removal. So I’ve been digging more into these, and I'll be going through the solutions that Dakota highlighted in more depth.

My question with you is, which ones do you want to hear about?

(As a refresher here’s what’s covered in the primer: Stratospheric aerosol injection, Marine cloud brightening, Cirrus cloud thinning, Mixed phase cloud thinning, Surface albedo modification, and Space-based reflectors.)

Looking forward to your thoughts!
